RERAILING-FROG.

Specification of Letters Patent.

Patented Nov. '7, 1911.

Application filed February 14, 1911. Serial No. 608,564.

To all whom it may concern:

Be it known that I, JOHN L. NICOLAI, a citizen of the United States,residing at Alliance, in the county of Boxbutte and State of Nebraska,have invented certain new and useful Improvements in Rerailing- Frogs;and I do declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

My invention relates to a rel-ailing frog and. has for its object toprovide a device for assisting the wheels of a railway or like car backonto the rails from the level of the road bed.

My device comprises more particularly a pair of frogs, one for use onthe outside rail and one on the inside rail, which are slightlydifferent in construction in order to adapt them for use with the carwheels having oppositely disposed flanges.

It is a further object of my invention to provide the improved detailsof structure hereinafter described and illustrated in the accompanyingdrawings, wherein Figure I is a perspective view of a railway trackhaving rails equipped with my improved frogs. Fig. II is an enlargedplan view of the outside frog member. Fig. III is an end view of thesame. Fig. IV is a plan view of the inside frog member. Fig. V is an endview of the same. Fig, VI'1s a vertical section on the line VIVI, Fig.II, showing the adjustable supporting blocks.

Referring more in detail to the parts 1 designates railway rails whichare set on ordinary ties 2 and adapted for carrying the flanged wheels3, these parts being of the usual and well known construction.

41 designates the outside frog member which is preferably constructed ofwrought iron and has inclined track-ways 5 terminating in a centralhorizontal section 6. At the inside of the track-ways are guard sections 7 which, when the apparatus is in place, extend up along the sideof the rail and are turned laterally to provide a horizontal hangermember 8, that is adapted to extend over the top of the ball of the railand has a depending flange 9 that hangs on the inside of the rail andretains the frog in place. With the outside frog the horizontal tracksection 6 is in the same plane with the hanger member 8, so that theflange of a wheel running up the track-way may pass onto the horizontalsection and thence over the hanger member to reach its position at theinside of the rail without interruption. The track ways are preferablyflaring toward their lower ends and have upturned flanges 10 at theiroutside edges, which are inclined upwardly and outwardly therefrom.Formed integrally with the frog, at the outer side thereof, are lugs 11having apertures for receiving the spikes 12, by which the frog may besecured to the cross ties. In order to accommodate the vfrog to rails ofdifferent heights, I prefer to make thesame adjustable by providing itsunder surface with stepped shoulders 13 and using blocks 14 havingstepped shoulders 15 for taking into the frog shoulders and forsupporting the frog. In order to anchor the parts together, I providethe blocks with sockets 16 and the frog with apertures 17, so that a pin18 may be dropped through the apertures into the sockets and hold theparts together without interfering with the travel of the wheels on thefrog. It is apparent that with this construction the block may hestepped inwardly or outwardly relative to the inclined track ways toprovide vertical adjustment for the frog.

While I have been describing the con struction of the outside frog, thisdescription answers equally well for the inside member with theexception that the plane 6, between the track-ways 5 of the inside frog,is set down from the horizontal hanger parts 8 a distance equal to thewidth of the wheel flange, so that when the wheel runs up the trackwayto be replaced on the rail,'the flange will engage the side face 8 ofthe hanger part and be turned onto the rail.

In order to obviate misplacement of the frogs by the engagement of thewheels therewith, I prefer to bevel the ends of the sides 7 and hangerparts 8, as illustrated, so that should the wheel or flange lie close tothe rail, it will be moved over onto the trackway when it engages thefrog and thereby obviate Inisplacement of the frog.

In using the frogs to replace a car that has run off of the track, theyare hung on the same side of the rails. The car is then moved forwardlyso that the flanges engage the inclined track-ways of the frogs and arecarried up on the track-ways until the flange of the outside wheel movesover its hanger and drops inside of the rail; the inside wheel moving upits track-way until the wheel flange engages the partof the hangerdepending over the inside of the rail ball and is turned thereby, sothat it will travel directly overv the rail.

' With a low rail, the adjusting blocks may be set back under theinclined track-ways, so that the top of the frog will be at the properheight for a low rail. With a high rail the blocks may be movedoutwardly so that the frog is elevated.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters-Patent is 1. A rerailing frog comprisingvertically adjustable inclined trackways having a plane parttherebetween, a hanger part for supporting the frog on a rail, and anupturned flange on the outside edges of the track-ways and plane part.

2. A rerailing frog comprising vertically adjustable inclined track-wayshaving a plane part therebetween and having guard sections at its inneredges, a hanger integral with the guard sections and plane part andprovided with a keeper flange, and a flange at the outer edges of thetrack-ways, substantially as set forth.

3. A rerailing frog comprising vertically adjustable inclinedtrack-ways, and a hanger, said track-ways being oppositely disposed andterminating in a part in the plane of the hanger, and an upturned flangeon the outer edge of the track-ways, for the purpose set forth.

4:. A rerailing frog comprising vertically adjustable inclinedtrack-ways and a hanger, said traok-ways being oppositely disposed andterminating in a part in the plane of the hanger, and outwardly inclinedupturned flanges on the outer edge of the track-ways, for the purposeset forth.

5. A rerailing frog comprising vertically adjustable inclinedtrack-ways, a hanger connected with the track-ways, and means forsupporting the track-ways at variable heights, for the purpose setforth.

6. A rerailing frog comprising inclined track-ways, a hanger connectedwith the track-ways, said track-ways having stepped shoulders on theirunder surfaces, blocks having stepped shoulders adapted for adjustablecooperation with the shoulders on the track-ways, and means foranchoring the blocks to the track-ways.

7. A rerailing frog comprising vertically adjustable inclinedtrack-ways, a hanger connected with the track-ways, upturned flanges onthe outer edges of the track-ways, and lugs on the outer side of thefrog having apertures whereby the frog may be secured to cross ties,substantially as and for the purpose set forth.

8. A rerailing frog comprising vertically adjustable inclinedtrack-ways, a hanger connected with the track-ways and adapted to extendover the ball of a rail, the ends of the hanger being beveled,substantially as set forth.

9. Rerailing frogs arranged in pairs, both members comprising hangersand having vertically adjustable inclined track-ways disposed toward acenter, the track-ways in the outer member terminating in the plane ofthe hanger, and the track-ways of the inner member terminating below theplane of the hanger, substantially as and .for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
